Hi, I've designed a circuit to produce a high voltage, high frequency sine wave from a low voltage square, produced by a microcontroller(Stellaris Launchpad). I've used a simple LC oscillator as a voltage magnifier. Voltage input to LC circuit = 3.3v (peak to peak) Voltage out = 54.42v (peak to peak) Resonance frequency = 355kHz The voltage generator produces a square wave Vmax=3.3v, Vmin=0v, with an internal resistance of 20k ohms at a frequency of 355kHz. Duty cycle is 50%. to simulate the microcontrollers output pin. The buffer IC used, is the LMH6321. Is this circuit effective? Are the
